Dell dimension issue: system is gone off all of sudden.. it looks like there is a problem with the add on card which consists 2 USB ports and microphone and headset speaker.... but this card is connected to the supply of power button


Answers :

It seems likely that you have somehow dislodged/interupted the graphics card GUI, which enables windows to come on the screen. Without this, the system will not boot properly due to the fact that your CPU is looking for it and cannot find it. You may want to double check to see if that card is in properly. Also, did you download driver for the new card? If not the right driver, it won't work. Another thing to check could be the IRQ I/O addresses (go to device manager/advanced) If they are not assigned a number, they won't work either. You can always hit F1 (it may be different on your comp, try f8 or f12) after you hit power switch, to see if it will give you the boot info before your OS starts up. Of course, you will not be able to see it if you have no video. Try to listen to the comp when turning it on. How many beeps does it make? It should only make 1, if it is making more, or a long one, you can find out problem that way.
